` NoRRIs E. GooDRICH, or BATTLE CREEK; MICHIGAN, lAssIGNoB/To sANITARIUI/f EQUIiMENTCoMPANY, or BATTLE CREEK, MICHIGAN MASSAGING MACHINE Y Application med Mays, 192s;` serial No. 274,721.

The main objects of thisfi'nvention` are: First, to provide an improved massaging machine of thetype employing crank disks With means for connecting the applicator directly thereto which prevent entangling ofthe applicator and eliminate `vvear there from. ,l

Second, to provide a structure having these advantages in Whichthe stroke may be re'a'dily'adjusted o'r varied. f

Third,to provide an improved applicator which is compact and' at the same time has substantial power.

Objects pertaining Lto details and economies of my invention will appear from'` the description to follow. Theinvention is defined in the claims. l y

A structure embodying Vthe features of my invention is clearly illustrated in the accompanying drawing,` in which:

F ig. lisa vertical section onA a line Corresponding to line' 1-1 of Fig. 2. A Fig. 2 is a view with the cover removed and partially sectioned on line 2;2 ofrFigs.

, Fig. S is an enlarged detail ofthe crank and applicator coupling means.y

' Referring to thedrawing, thebody portion 1 of the housing is preferably a borr- V like casting and is adapted kto receive a cover 2. IVithin the housing I mount the motor 3. The `motor shaft 4 is provided With a pinion 5. Disposed parallel with the vmotor shaft is a driven shaft 6 having `a a gear 7 thereon meshing With'the pinion 5.

Thek shaft is supported by bearings 8 mounted Within the housing in spaced relation to the ends of thesliaft. The shaft is alined with openings 9 in the side Walls of ythe housing which are of such dimensions as to receive the crank disks 10.

The crank disks 10 arey provided with radial undercut or dove-tailed-grooves `11A in Which the heads 12 of the crank pin studs y13 are engaged. The body members 14 of the crank pins are threaded upon the studs to clamp the sides of the disk, thereby clamping the crank pins in their adjusted positions. These body members have handhold portions 15 which may be grasped for loosening and clamping the crank pins .in

place. n

Bearing-studs V16 project from the outer ends of the body members and are dis posed in thecentral bores 17 of the head members and secured therein by the pins or keys 18. Y

Coupling members 19 are. provided havving central outwardly projecting studs. .20

rand inwardly opening recesses 21 adapted to receive thebearings by which the coupling members are rotatably supported and are .connected to the bearing studs. The inner ball race orbearing member 22 is secured to the stud 16 byupsetting at 23, thereby clamping the bearing member against the shoulder 24. The outer bearing member 25 is secured to the coupling member kby upsetting the same at 26. The bearing balls 27 are provided to coact with these bearing members. A thrust bearing member 28 is disposed between the coupling member and the end of the 'handhold portions y15. V.A

recess 29 in the port-ion 15 encloses the inner end ofthecoupling member. v `The applicator attaching hooks 30 are provided with eyes 31 engaging. the studs for rotative movement therein.` These eyes,

however,` are engaged by the spring Washer A 32, the tension of which is adjusted by means of nuts 33. The applicator engaging hooks are thus normally held in a fixed relation on the coupling members,y but in' the event of undue stress or rotate.

I have'illustrated and described my improvements in an embodiment Which Iregard as very satisfactory. I have not attempted `to illustrate and describe other embodiments or vadaptations of my improvements Which I contemplate as I believe the disclosure made Will enable thosefskilled in the art to Vembody or adapt the same as may be desired. e v l Having thus described my invention What I claim as newand desire to secure by Letters Patent is: i
